I want to be able to add a bar chart on Kibana which displays a count of users (identified by `name`) which have a total of more than 0 in `total_a` (with total of 0 for `total_b`) and column for those with a total of more than 0 in `total_b` (with total of 0 for `total_a`). So the calculation needs to take place across all documents with a given `name`.

```
[{
  "name": "foo",
  "total_a": 10,
  "total_b": 0
},
{
  "name": "foo",
  "total_a": 0,
  "total_b": 10
}, 
{
  "name": "bar",
  "total_a": 50,
  "total_b": 100
}]

```

Is this possible?

Have you tried creating a horizontal or vertical bar chart with a split series on name and a subsequent split series using a filter aggregation that filters by your clause?  
or directly a single bucket filter aggregation with name and total\_a \> 0 ?
